Radioactive therapy targets Hard-to-Treat kidney cancer
NCT ID NCT06959433
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 3 trial tests a radioactive drug called Lu-177 PSMA in 20 people with metastatic clear cell kidney cancer that has worsened after at least two prior treatments. The drug is designed to seek out and destroy cancer cells while limiting damage to healthy tissue. Researchers will monitor side effects and measure tumor response using standard criteria.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lu-177 PSMA-617 (a radioactive drug that targets cancer cells)
- What this could lead to
- If it works, this could offer a new treatment option for people with advanced kidney cancer who have run out of standard therapies.
- What could go wrong
- This is a very small early-phase trial (only 20 people), so results may not apply to everyone. The treatment involves radiation, which can cause side effects like damage to kidneys, liver, or salivary glands.
